Crop rotation is also vital in organic gardens. By changing the type of plants grown in each bed annually, gardeners prevent the buildup of pests and diseases while maintaining soil balance.

Pest management in organic gardening relies on natural methods. Companion planting, where certain plants are grown together for mutual benefit, can deter pests. Marigolds, for instance, repel nematodes, while basil planted near tomatoes enhances growth and flavor. Beneficial insects like ladybugs and lacewings help control aphid populations, reducing the need for pesticides.
